AB - Fibers made of elements such as carbon, aramid and glass have higher mechanical
properties than other conventional textile fibers and they enable the production of light weight
composites as end products. Furthermore, commingling hybrid yarns generally have a characteristic
feature so that their components are distributed homogeneously enough over the yarn cross section. A
normal air texturerising machine was modified to produce commingling hybrid yarns for test samples.
Different process parameters were applied to produce the hybridized yarn samples. However, these
process parameters turned out to have little effect on the filament distribution over the hybrid yarn
cross section in terms of homogeneity. The analysis in this paper is focused on the pattern of mixing
of filaments over a cross section of hybrid yarns according to different combinations of reinforcement
and matrix filament yarns through microscopic view. The volume content of filament in hybrid yarn
cross section was maintained at 50% for both reinforced and matrix, and the hybrid yarns count at 600
tex throughout experiments. It was concluded from the experiments that the diameters of
reinforcement and matrix filaments have strong effects on the pattern of mixing of filaments over a
cross section of hybrid yarns such that the hybrid yarns with more or less equal diameters of
reinforcement and matrix filaments showed considerably even distributions over the hybrid yarn
cross section.
